Functions

• Origin point setting (ABS measurement system):
  Resets the ABS origin at the current spindle position to
  the minimum value of the measuring range and switches
  to ABS mode.
• Zero-setting (INC measurement system):
  A brief press on the ZERO/ABS button sets display to
  zero at the current spindle position and switches to the
  incremental (INC) measuring mode. A longer press resets
  to the ABS measuring mode.
• Hold:
  Pressing the HOLD button freezes the current value
  in the display. This function is useful for preserving a
  measurement in situations of poor visibility where the
  instrument must be moved away from the workpiece
  before the reading can be recorded.
• Function lock:
  This function allows the PRESET (origin point setting)
  function and the ZERO (zero-setting) function to be
  locked to prevent these points being reset accidentally.
• Auto power ON/OFF:
  The reading on the LCD disappears after this instrument
  is idle for about 20 minutes, but the reading and
  measurement mode are retained. Turning the spindle
  causes the reading to reappear.
• Data output:
  Models equipped with this function have an output port
  for transferring measurement data to a Statistical Process
  Control (SPC) system.
• Error alarm:
  In case of an overflow on the LCD or a computing error,
  an error message appears on the LCD, and the measuring
  function stops. This prevents an instrument from giving an
  erroneous reading. Also, when the battery voltage drops to
  a certain level, the low-battery-voltage alarm annunciator
  appears well before the micrometer becomes unusable.
